Battery Panasonic or Duracell

The best lead acid type of battery is a Duracell/East Penn hybrid/house AGM deep cell. These have thicker plates and are typically used for RVs and boats. They can tolerate deeper discharge and are less susceptible to damage (AGM). They sacrifice a little instantaneous current output, but that's not needed on an EV.

We’ve always had luck with Duracell in our cars.

I had a 2004 Scion xb back in the day that was made in Japan. Had to get rid of it after the engine developed excessive oil consumption. Had a hell of a battery in it. Panasonic brand.

The replacement battery I bought was a Duracell from Sam’s Club. Fit and worked fine.

Yeah, the oem Panasonic battery is easy to kill. I replaced mine (2022 Turbo) with an AGM type. Most all batteries are made by Johnson Controls, under different names. The cheapest price I found was $179 with a 4 year warranty at Walmart. Everstart Platinum group 35. Was a 10 min job to remove and replace. They can even test your old one. The agm type is in the deep cycle family, it can be discharged quite a bit without any issues, the stock battery (flooded acid type) is easy to damage.

My 2019 Mazda 3 died on me randomly a couple months ago. The dealership ran a test on it and it came out fine. I changed it anyway as it was a stock 5 year old battery. It’s been fine since, even in the -20°C temps where I am.

Not near Utah but here on the west coast I use Powersonic or Genesis or Yuasa with good luck. For some reason all the Duracells I have purchased over the years fail about a year out of install.

I'm not putting a Duracell in my car, they can't even make a double A that doesn't leak within the year.

They use some crap Panasonic battery.

Just had to replaced my battery in my 2022 Mazda 3. I’ve always heard people say the batteries are crap in these cars. There’s no way you should be replacing a OEM battery yet. They use some crap Panasonic battery.
